Petra,

It happened again. I had another one, but it was in the left ear. I did not report it here. But there...

And then 3 days later..

This stuff is a bit creepy to me. Not sure why. I don't get ear tones very often. Have not had the flu bug or anything. If this works, as you say, I'll have to prove it to myself. There is a place at your site to report these?

Thanks
Glen
